Development and evaluation of habitat suitability criteria for use in the instream flow incremental methodology: Instream Flow Information Paper no. 21

This information paper concentrates on only one of the biological components of the IFIM, the development and evaluation of microhabitat criteria. Other equally important biological components include information related to water quality, temperature, trophic relationships, and population dynamics. These subjects are beyond the scope of this paper, which is fortunate because the topic of microhabitat criteria is large enough by itself. These other items will be discussed only to the extent that they may affect microhabitat usage.
